I am the creator of the zoro auto-focus userscript, which unfortunately is no longer functioning. I don't know shit about coding, so I don't even know how the script even worked in the first place. Essentially, I condensed the 9anime bingwatcher+ script as much as possible. I believe the script worked by automatically clicking on an element of the video player repeatedly to get the focus on the video player. The script doesn't work anymore because of the change in the server (video player).
